MACHINE FOR SENDING WAGON AXLES.

SPECIFICATION forming part of Letters Patent No. 391.6%9, dated October 23, 1888.

Application filed July 2-5, 1886. Serial No. 280,942. (No model T0 (tZZ whom it may concern;

Be it known that 1, WILLIAM SOHWINGEN, of WVilkesBarr, in the county of Luzerne and State of Pennsylvania, have invented certain Improvements in Machines for Bending Wagon-Axles, of which the following is a specification.

This invention relates to machines for use in the formation of cranked axles for wagons and carriages; and it consists in a machine of peculiar construction for imparting to the end of the bar two angular bends.

In the accompanying drawings, Figure 1 is a perspective View of the machine. Fig. 2 is a longitudinal central section of the same. Fig. 8 is a crosssection on the line 00 m.

Referring to the drawings, A represents a rigid base frame or plate,whieh may be of any appropriate form, provided on its upper surface with longitudinal guides a, which give support to slides B and D. The slide Bis adjustable horizontally by means of a horizontal screw, 0, swiveled in the frame and provided with a hand-wheel or equivalent devices by which to turn it. The slide D is adjustable horizontally in like manner by means of a screw, E, swiveled in the opposite end of the bed or frame and provided with a hand-lever. By means of these two screws the two slides may be moved to or from each other. The slide B is provided with an upright rigid arm, b, the upper end of which is forked and provided with an anti-friction pulley, b Near the base of this arm the slide is provided with an anvil-block, b,which may be fixed rigidly thereto, but which is preferably sustained, as

shown, by springs b so that it may yield vertically to a limited extent. The upper face of this anvil b stands at a right ang1e,or substantially so,to the upright face of the arm I), and is designed to cooperate therewith in supporting the axle on the outside during the bending action. The slideD has a vertical face, at, opposite the inner vertical end of the anvil b, and has at the sides of this face vertical cheeks or flanges d,to assistin sustaining the axle in a vertical position. An outreaching arm on the under side of the slide D serves to guide a verticallyadjustable step, d intended as a bearing or support for the lower end of the axle when it is first inserted in the machine. This step is provided with a threaded shank passing downward through the arm. It is sustained by a strong spring, (Z and may be drawn down to any required point by means ofa nut, d, on the lower end.

F represents a swinging former or bendingarm mounted on and operated by a horizontal shaft, f, mounted in cheek-platesf on the slide D, and provided with a handle, f, by which it may be turned downward from the vertical position shown in Fig. 2 to a horizontal position overlying the anvil b. The cheek-plates f, in which the former Fis mounted, areprovided with the vertical slots 9, through which and the slide D set-screws G- are passed, this construction permit-ting the former .F to be adjusted vertically. This arm or former F is provided at the two sides with checks or tlangesf and f, the latter being pressed outward, as shown in Fig. 3, by an underlying spring), and held adjustably in position by a set-screw, f i

In making use of the apparatus the arm or former F is turned to a vertical position, as shown in Fig. 2, and thestraight rod to be bent placed in a vertical position against the face of the former F and anvil b with its lower end resting on the support d. The slide B or the slide D is then advanced until the bar is clasped firmly between the vertical face of the anvil b and the vertical face (2, after which the former F is turned downward,the effect being to bend the rod or bar at a right angle over the corner and downward upon the upper face ofthe anvil b, and also to bend it a'second time into the angle between the vertical face of the arm I) and the horizontal face of the anvil b, as indi cated in dotted lines.

The roller 1) is designed to reduce the frietion, and may be omitted, if desired. As itis preferred to leave a short curve in the corner, I commonly round the corner of the anvil b and the end of the former F; but this feature may be omitted.

By adjusting the rest d vertically, and by adjusting the slides horizontally,the machine may be adapted to form the bends at different distances apart, according to the length of the cranked portion required.

Either of the two parts B or D may be fixed rigidly in position; but it is preferred to make both adjustable, as herein shown.

Having thus described my invention, what I claim is- 1. In an axle-bending1nachine,the combina- IOO tion of a block or slide, D, a swinging former, 4. The combination of the frame A, the ad- F, and the slide B, having an upright arm, justing-screws G E, the slide B, having arm I) and anvil b. and anvil b, and the slide D, having the step 2. In combination with the support D and d and pivoted former F.
